v0.12.1

• mq-sendmail now accepts default CLI parameters from cronie (9438e41). This means cronie can send emails containing the output of cron jobs if mq-sendmail is available under /usr/sbin/sendmail.
• The RPM package now uses the alternatives mechanism to provide implementations for /usr/sbin/sendmail and /usr/bin/mail so that cronie and dnf-automatic can send their emails via mailqueue-runner.
